Mongo/Node JS，如何更新数据库中的记录？

Question

I have a feature in my program where in there is a job that will get file every 2 hours and parse to json and then add those data to the database.

Using upsert I was able to create record if no match and then update records that matches, there is no problem with this.

The file i am getting every 2 hours has dynamic values where it the total data depends, sometimes some data is reduced, sometimes new data is added.

So for example first 2 hours the file contains 3 records I was able to add 3 records to the database and the database now has 3 current records.

Current Record in the database

value: {
    "userId": 1,
        "id": 1,
            "title": "delectus aut autem",
                "completed": false
},
"userId": 2,
    "id": 2,
        "title": "delectus aut autem2",
            "completed": false
  },

"userId": 3,
    "id": 3,
        "title": "delectus aut autem3",
            "completed": false

}

But on the next 2 hours there are only 2 records from a file one was removed. So since there is match it will update the 2 records

JSON File Data

 value: {
        "userId": 1,
            "id": 1,
                "title": "delectus aut autem",
                    "completed": false
    },
    "userId": 2,
        "id": 2,
            "title": "delectus aut autem2",
                "completed": false
      },

It would also update all record that was removed in the file but present in the databse set completed == true

So the final record in the databsae would be like this

Userid3 completed value would be now equal to true.

 value: {
        "userId": 1,
            "id": 1,
                "title": "delectus aut autem",
                    "completed": false
    },
    "userId": 2,
        "id": 2,
            "title": "delectus aut autem2",
                "completed": false
      },

    "userId": 3,
        "id": 3,
            "title": "delectus aut autem3",
                "completed": true

    }

My Query

var myQuery = { 'id': value.id }
//Update existing data ang create if no data found using upsert
Person.model.findOneAndUpdate(myQuery, value, { upsert: true }, function (err, doc) {
    if (err) {
        console.log("[ERROR]", err)
    }
})

findOneandUpdate won't work like that if you want to update multiple documents. You should be using bulk update for that. Here is the link

I hope it helps. Thanks
